Massive Osteolysis of the Mandible in Gorham's Disease: Our Case Experience.

Vanishing bone disease is an exceptionally rare condition marked by the progressive loss of bone, ultimately leading to its complete disappearance. The cause of this disease remains unknown, and it primarily affects the axial skeleton, pelvis, and humerus. Due to its atypical presentation and rarity, it is often mistaken for other disorders, making an accurate diagnosis challenging and typically a process of elimination. Gorham's disease has been documented in the maxillofacial region, with most involving the mandible. We present a case involving a 14-year-old male patient who exhibited Gorham's disease in the right mandible, characterized by the loosening of teeth.
